Harold Metcalfe is such a person:
THIS IS QUOTED FROM HAROLD:
"I've often been asked, 'What do you do now that you're retired?'
Well...I'm fortunate to have a chemical engineering background and one of the things I enjoy most is converting beer, wine and whisky into urine.
It's rewarding, uplifting, satisfying and fulfilling. I do it every day and I really enjoy it."
Harold is an inspiration to us all.
